"""
OpenAI Guardrails Example with Traceloop SDK

This example demonstrates how to use OpenAI's guardrails library with
OpenLLMetry tracing. The guardrails library wraps the OpenAI client to
provide automatic input/output validation and safety checks.

The trace context is properly maintained across the wrapper's internal calls,
ensuring complete observability of the request flow.
